摘　　要：为了提高摄像机标定精度和降低标定的复杂度,在Tsai两步标定法的基础上,提出了一种改进标定法.该方法采用分步标定的思想,以创建的平面模板为标定物,利用共面点便可线性求解出摄像机的内外参数.建立的摄像机模型考虑了径向畸变,有利于提高标定精度,标定过程只需要线性计算,避免了繁琐的非线性优化.In order to improve the camera calibration precision and reduce the complexity,an improved calibration method is proposed based on Tsai two steps calibration method.This method adopts calibration thoughts,taking created Plane template as an object,and using linear solution,inside and outside the camera parameters can be computed.The camera model considers the radial distortion,be helpful for improving calibration precision.The calibration process only needs to linear computation,avoids tedious nonlinear optimization.
